Echo wird in IF nicht ausgeführt

EuroCent · 31. Dezember 2016

@robotsox
Der fehler könnte aber sein, dass du dieFunktion aufrufst, bevor das Script überhaupt existiert

Überprüfe dass mal.
Wenn es der Fall ist, dann dies per if-else ebenso aufrufen.

robotsox · 1. Januar 2017

wie kann ich denn das am besten prüfen?

EuroCent · 2. Januar 2017

In dem du schaust dass die funktion erst dann aufgerufen wird wenn es true bzw. false wieder gibt.
Ansonsten hast du nach wie vor das Problem ^^

Wann genau rufst Du die Funktion denn das erstmal auf?
Unabhängig davon ob dies in deiner PHP Datei steht.

Zeig uns mal den Quellcode der Passwort-Vergessen-Seite.
Eventuell ist da ein Fehler erkennbar

robotsox · 2. Januar 2017

Habe anbei mal die 2 Dateien angefügt.
Mal schauen ob wir zusammen das Problem lösen können

Code:

!function ($) {
    "use strict";
   
    document.querySelector('button.passwd-reset').onclick = function () {
        swal({
            title: "<small>Passwort zurücksetzen</small>",
            text: 'Sie haben hier die Möglichkeit ein neues Passwort anzufordern',
            type: 'input',
            html: true,
            showCancelButton: true,
            closeOnConfirm: true,
            animation: "slide-from-top",
            inputPlaceholder: "Benutzername oder E-Mail Adresse",
        },
                function (inputValue) {
                    if (inputValue === false)
                        return false;

                    if (inputValue === "") {
                        swal.showInputError("Bitte geben Sie Ihre E-Mail Adresse oder Benutzernamen ein!");
                        return false;
                    }
                    var xmlHttp = new XMLHttpRequest();
                   
                    xmlHttp.open( "GET", "../login.php?methode=passwd_reset&user="+inputValue, true );
                    xmlHttp.send();
                });
    };


}(window.jQuery);

function user_passwd_reset_fail()
{
    swal("Fehler", "Es konnte kein neues Passwort generiert werden, bitte versuchen Sie es später erneut!", "error");
}

function user_passwd_reset_success()
{
    alert("test");
    swal("Erledigt!", "Bitte kontrollieren Sie Ihr E-Mail Postfach!", "success");
}

Setzte deinen PHP-Code vor das </body> Element und es sollte funktionieren.

Und: Muss eine PHP-Datei nicht mit "<?php" beginnen? Oder war das nur früher?

robotsox · 2. Januar 2017

Das mit dem PHP code vor dem HTML hane ich bereits versucht, leider ohne Erfolg

DexXxtrin · 2. Januar 2017

Bei mir kommt ein js popup mit dem Inhalt "test".
Musste den Code entsprechend anpassen, bzw. alles, was mit der DB zu tun hat auskommentieren und anstelle von if($counter == 1) einfach if(true).

DexXxtrin hat gesagt.:

Der PHP-Code ja, die ganze Datei nicht unbedingt.
Eine ".php"-Datei könnte sogar nur HTML enthalten, ohne eine Zeile PHP.
